Army & Navy - Lessons of the Cumberland

Along Tennessee's Cumberland River, Army
maneuvers reached their climax. Foot soldiers and jeepers, tankers,
airmen and artillerymen tried every trick, threw everything they had
except real ammunition, tramping out a problem. The problem: can a tank
blitz be slowed and even halted. Answer: by well-organized opposition,
yes. The engineers with tank traps did the job of slowing, but the star
of the action last weekas in the whole two previous months of
maneuverswas the Second Army's tank destroyer battalion. The
Cumberland's will-o'-the-wisp struck, destroyed, disappeared and struck
again.
